FAR 46.105 Quality Checklist: Tendering Conforming Work
Federal contracting places direct accountability for workmanship, material verification, and final compliance squarely on the contractor. Under FAR 46.105 Contractor responsibilities, bidders must structure their proposals to handle active quality control rather than treating inspection as a task handled solely by federal personnel. Using a structured bid-day checklist based on these regulatory obligations allows trade contractors and estimators to price the required management systems, test procedures, and vendor oversight before submitting a binding offer.
Checklist Item 1: Verify Direct Quality Control and Acceptance Duties
Before submitting a number, estimators must confirm that the project budget carries the resources necessary to control the quality of all supplies or services provided under the agreement. FAR 46.105 establishes that the contractor is responsible for carrying out contract obligations by controlling quality and tendering to the government for acceptance only those items that conform to contract requirements. A solid bid day checklist should account for the supervisory time needed to prevent defects from reaching the federal contracting officer or representative.
Tendering work means presenting completed milestones, subassemblies, or materials for formal government sign-off. If your proposal assumes that government personnel will point out defects for your crews to fix later, the bid is fundamentally mispriced. The primary contractor duty is ensuring that nonconforming items are caught and resolved internally prior to any tender for acceptance.
Checklist Item 2: Audit Supplier and Vendor Quality Control Systems
Federal quality obligations do not stop at your own jobsite operations or internal fabrication shops. Under FAR 46.105(a)(3), the contractor must ensure that vendors or suppliers of raw materials, parts, components, and subassemblies have an acceptable quality control system in place. Bid-day reviews must verify that downstream supply chains meet these expectations:
- Raw material suppliers maintain verified internal checks for grade, composition, and physical tolerances.
- Component and subassembly manufacturers operate documented quality processes before delivering elements to the site.
- Lower-tier trade partners can demonstrate consistent quality control methods aligned with prime contract obligations.
When requesting quotes from material distributors or trade partners, estimators must clarify whether supplier pricing includes their quality control documentation, preventing unexpected costs after award.
Checklist Item 3: Budget for Substantiating Evidence and Technical Records
Meeting technical specifications is only half the battle on a federal project; proving compliance through documentation is equally critical. FAR 46.105 requires contractors to maintain substantiating evidence when specified by the contract, demonstrating that supplies or services conform to contract quality requirements. Contractors must also furnish this evidence to the government as required.
Furthermore, quality control covers technical documentation, which includes drawings, specifications, handbooks, manuals, and related technical publications. Your estimate must carry administrative hours for compiling, indexing, and submitting these records throughout the construction timeline rather than scrambling to produce paperwork during final closeout.
Checklist Item 4: Scope Required Testing and Contractor Inspection Programs
A contractor may be required to provide and maintain an inspection system or program for the control of quality that is acceptable to the government, pointing back to the standards in FAR 46.202. In addition, the contractor is explicitly responsible for performing all inspections and tests required by the contract, except those specifically reserved for performance by the government under FAR 46.201(c).
Failing to price necessary test equipment, field examinations, or technician labor leaves a contractor exposed to cost overruns. It also increases the danger of formal rejections, rework delays, or payment disputes under related clauses covering how the government handles defective work. Make sure every required test listed in the solicitation is assigned either to your own crews, a dedicated testing vendor, or confirmed as reserved for the government.
Checklist Item 5: Monitor Physical Operations, Packaging, and Services
FAR 46.105(c) outlines the broad areas to which contractor quality control may relate. Estimators should confirm that field management costs address each applicable operational phase:
- Manufacturing processes to verify products meet all technical requirements.
- Drawings, specifications, and engineering changes to align methods with technical standards.
- Testing and examination practices and equipment to ensure optimum evaluation of characteristics subject to inspection.
- Reliability and maintainability assessments, including life, endurance, and continued readiness.
- Fabrication and delivery processes to guarantee only conforming items are tendered.
- Preservation, packaging, packing, and marking to safeguard materials against damage before delivery.
- Procedures and processes for services to confirm that field operations achieve specified performance requirements.
